The capital cost for heap leaching/SX/EW was reported by Peacey et al. (2004) to be around US$4000 to US$5000 per annual ton of copper cathode for plant capacities between 40,000 to 200,000 mt/y. The capital cost was observed to split about one third for each heap/SX/EW operation. Heap leaching capital cost included open pit mining, ore ...

Sepon mine to operate the first modern underground mine in Lao PDR. With a mineral resource of 9.5 million tonnes and projected ore production to increase from 400,000 tonnes in 2023 to 1.2 million tonnes per annum thereafter, the "Discovery Deeps Underground Mine" is expected to extend Sepon's mine life for at least another seven years ...
An alternative to recycling the bleed is to electrowin the copper from the bleed; this low copper, high acid solution can then be sent to either the raffinate for higher leach recovery, or E1 for higher SX recovery. When using the untreated EW bleed (approximately 5 g/L copper) to leach the ore, it is less effective than a copper-free leach ...
Phoenix acquired an 80% interest in the historical Empire Mine property in 2017 and, based on a total of 320 drill holes, an oxide resource was completed in late 2017. A NI 43-101 compliant PEA (preliminary economic assessment) for an open pit heap leach solvent extraction and electrowinning ("SX-EW") mine was completed in April 2018.
SX-EW (solvent extraction-electrowinning) is the cathode copper production technology used in the KGHM International facilities. Page tools SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid.
extraction2 (SX). Both processes are part of a larger scheme often known as hydrometallurgical recovery of copper. Both documented and undocumented fire and explosion incidents historically indicate that the EW process represents a realistic fire and explosion hazard. The conclusions of this study are consistent with these historical experiences.
2. The SX mix boxes were all located at the same end of the settlers. 3. Pump-mix impellers were not used and Inter-stage transfer was by pumping. 4. Copper was deposited on copper staring sheets in EW. Copper SX/EW Basic Principles & Detailed Plant Design 14 RANCHERS BLUEBIRD, ARIZONA, 1965 FIRST COMMERCIAL COPPER SX-EW OPERATION Copper …
The SX plant was built with four parallel trains each having three extraction and two stripping mixer-settlers. The total flow capacity was 4,921 liters per minute (l/min) of aqueous leach solution using a 1:1 organic to aqueous ratio. The design was typical first generation with single-stage round mixers and long, rectangular settlers.
copper sulphate to an EW plant at another location with lower power unit cost. The disadvantage is the problem of recycling the sulphuric acid regenerated in EW back to the leach/SX facility. Cementation Cementation with scrap iron is a long-established process which largely met its demise with the advent of SX/EW.
Outotec announced during MINExpo in Las Vegas last week that it has signed an agreement with Florence Copper Inc., a subsidiary of Taseko Mines (TSX: TKO; NYSE: TGB), to supply copper ...

A phenomenological steady state simulation model for a copper SX/EW pilot plant has been developed by Aminian et al. (2000). The simulation model uses variables that are not measured online in ...
operations. Twelve out of nineteen SX processes in our reference list (1) are or have been in use in Finland. A constant pursuit of better SX performance has resulted in an uninterrupted development work covering all aspects of the SX processes. In the early 90's the accumulated SX know-how had already passed a level, after which the keystone ...
Copper SX-EW technology Benefits • High process performance • State-of-the-art process technologies • Project and plant optimization • High availability and working ergonomics • Maximum safety and environmental hazard control Our solution for leaching, solvent extraction and electrowinning
Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes …

sheet of an SX–EW plant, we use the OutoCompact layout in our process design. In the OutoCompact layout, a loaded organic buffer is held in a loaded organic (LO) tank that is an active piece of process equipment in an SX-track. The wash water circulation and coalescence gates of the LO tank prevent contaminated aqueous residues being carried
Copper production from SX-EW rose from 0.8 to 2.0 Mt in the period 1993 to 1997 (Arbiter and Fletcher, 1994; Readett and Townson, 1997). In 2001, ...
Fig. 1 shows a possible layout of a SX–EW process used to recover copper from solutions produced by ore leaching. The process of Fig. 1 consists of two extraction stages followed by a stripping stage in closed circuit with an EW unit. The pregnant solution from the leached ore piles is mixed in a first mixer–settler unit with an organic phase carrying an …

The solvent extraction electro-winning process (SX-EW) is a hydrometallurgical means of extracting, purifying, and concentrating metals. SX-EW has continued to demonstrate successful use in effectively extracting and recovering copper from low grade and oxide ores. As a result, SX-EW has quickly become a staple in the copper industry; SX-EW is ...
